We use Tripp Lite's environment sensor peripherals in our Tripp Lite UPSs in telecoms where the temperature regulation isn't great. These things do the job, but they aren't great. The SMTP alerts and traps they send out when my thresholds are tripped don't mention what the value that tripped them is: They just say 'the humidity threshold was passed'. Does that mean it's too humid, or too dry? To combat this, I set up UnDPs to poll the OIDs that actually tell what the temperature/humidity levels are, and I'm graphing these values in each UPS' Orion page. I've been trying to take this a step further by getting rid of my SMTP and trap alerts, and setting up SAM alerts that I can at least customize to say "it's too humid (or dry)" based on my UnDP values.

The problem is, when I do this, the "This alert would be immediately on..." tip in the summary page always just shows the name of the poller causing the alert.

You won't see the node name in the summary as shown, but you can include it in the alert action itself. I use UNDPs to alert on APC UPS SmartTrim status and this statement in the alert works. Just use the insert variable tool to get the right variable for your instance. Set up the text around it as you want.

Hmm, thanks for that. This seems right (and obvious, can't believe that hadn't occurred to me), but when I enable the alert, I get ~46 emails about various devices that say they're overheating (testing on a similar scenario above, but using a UnDP for Xirrus device's internal temperature). But if I run the UnDP with Orion's tool, it only shows one device past my threshold (127F), and my table in Orion shows the same:

You're probably right, might just need to play with it more. We have 107 Xirrus APs monitored, so it's not like all of them are triggering the alert.
